About this gig

Slow pages, hydration errors, a hosting bill that keeps growing? I'll find out why and fix it, with before-and-after numbers.


I'm Ali, a Fiverr Pro engineer with 8+ years in React and Next.js, including data-heavy dashboards and public reporting tools.


WHAT I CHECK

  • Core Web Vitals and Lighthouse scores
  • Server vs client rendering, caching and data fetching
  • Bundle size, images and fonts
  • Hydration errors and React re-renders
  • Slow database queries and API calls
  • Hosting setup and cost on Vercel, AWS or Supabase


WHAT YOU GET

  • A plain-English report, ranked by impact
  • Fixes in your repo as reviewed pull requests
  • Before-and-after measurements on the same pages


HOW IT WORKS

  1. Share the repo and the pages that matter
  2. Audit report in 3 days
  3. You choose what I fix


I won't promise a score before I've seen the code. I will tell you exactly what's slowing you down.

I build AI-powered web apps, agents, and SaaS MVPs that ship. 8+ years of full-stack engineering (Next.js, React, TypeScript, Node, PostgreSQL) plus hands-on production work with OpenAI, Claude, and RAG pipelines. Founders come to me to turn an idea into a working product: auth, Stripe billing, AI features, admin dashboards, deployed and ready for users. Recent work: AI agent pilots, AI SaaS platforms, dashboards and CRMs for clients in the US and EU. 5.0 average across 60+ reviews, many from repeat clients. Tell me what you're building and I'll reply within an hour with a concrete plan.
